Serial port addresses
IBM Aptiva PCs have two built-in external serial ports
already installed in the computer. The connectors for
these ports are located at the back of your computer.
These ports can be used to connect a serial mouse,
serial printer, or other serial device, and to transfer data
between computers.
The built-in serial ports support these addresses and
interrupts:
If you are using and operating system other than
Windows 95, conflicts may arise if you add adapter
cards with serial ports or if you change the address
settings on your modem. You can resolve most of these
conflicts by using the Setup Utility to change serial port
addresses. See “Changing input/output port
configuration” on page 35 for more information.
